JOSEPH BODA, OF PLANO, ILLINOIS, ASSIGNOR TO INDEPENDENT HARVESIER COMPANY, OF PLANO, ILLINOIS, A CORPORATION OF MAINE.

HARVESTER-ELEVATOR.

To all whom it may concern:

Be it known that I, Josurrr BoDA,a citizen of the United States, residing at Plano, in the county of Cook and State of Illinois, have invented new and useful Improvements in Harvester-Elevators, of which the following is a specification, reference being had to the drawings, forming a part thereof.

'This invention relates to the structure of the elevator of a grain harvester, which consists in the features of construction shown and described as indicated in the claims.

In the drawings :Figure 1 is a rear side elevation of a portion of a harvester elevator equipped with this invention. Fig. 2 is a view of the same looking in the direction of the arrow 2 on the Fig. 1. Fig. 3 is a detail side elevation of the adjusting device which characterizes the invention, on a larger scale than the other figures.

The drawings show the elevator of a harvester, conventional as to general structure, comprising the lower elevator apron 1, and frame structure for the same represented by the side bar 4, rigidly mounted on the harvester frame, which is represented by the frame bars, 2 and 3. The upper element of the elevator comprises the customary apron, 5, with its lower and upper rollers, 6 and 7, journaled in the forward rigid side of the elevator, 8, and in the rear side bar, 8 Said upper elevator is overhung, as usual, so as to form the rearwardly open elevator structure which is desirable, and for this purpose the rear frame bar, 8 is supported by the customary bow, or C-shaped frame, 9, constituting a rigid part of the harvester, having its lower limb extending under the elevator and mounted rigidly in the harvester frame bars and its upper limb, 9 overhanging the elevator, the bow being sufliciently far rearward to allow for the passage of the heads of the longest grain. No other support for the rear bar, 8 on the upper elevator apron frame can be easily provided, and the effect of supporting said bar at the point at which it can be supported at said upper limb, 9 on the C- shaped, or bow frame,the latter being at suitable position for other purposes, considerably nearer the lower than upper end of the elevator,is that the upper elevator apron frame tends to sag at the upper rearward corner and also tends somewhat to sag generally downward longitudinally at the Specification of Letters Patent.

rear side; that is there is a tendency to distortion from rectangular form and also to distortion by twisting out of the true plane. In order that such distortion by sagging in elther manner mentioned, when it occurs, may be corrected, the rear bar, 8, on the upper elevator apron frame is secured to the upper limb of the bow frame by means of a two-membered hanger, comprising a bracket, 10, which is secured to the rear side of such frame bar, 8 by bolts, which take through slots, 10, elongated in the direction of the length of said side bar, so that the said bracket member may be adjusted longitudinally of the bar from time to time, such adjustment being adapted to compensate for the downward longitudinal sagging of said upper elevator apron frame. The other member of the hanger is a bracket piece, 11, which is provided with a suitable seat, 11, for fitting against the stubbleward side of the upper limb, 10 on the bow frame, to which limb said bracket member, 11, is securely bolted. The stubblewardly extending arm of this bracket is pivoted at 12 to an upwardly extending lug of the bracket, 1.0, and the grainwardly extending arm of the bracket, 11, is connected to the grainward, or lower end of the bracket, 10, by means of a threaded link, 13, which is pivoted to the said lower or grainward-extending end of the bracket, 10, and extends through the corresponding end of bracket, 11, that is provided with adjusting and securing nuts, 14, 14, at opposite sides of said end of the bracket, 11., through which the link extends. The nuts, 14, 14, it will be understood, may be adjusted to increase or diminish the distance between the opposed ends of the two bracket-s, 10 and 11, thus causing the rear side bar, 8 on the upper elevator frame to rock about the pivot 12. The adjustment ordinarily required, obviously will be an increase of the distance between the grainward ends of the brackets, 10 and 11, causing the side bar, 8*, to be rocked in direction for swinging its upper end up and grainward away from the lower elevator apron, thus compensating for the downward sag of the upper rear corner.

I claim 1. In a harvester elevator, in combination with the lower elevator apron, an upper elevator apron and frame which at the rear end is suspended above the lower apron for forming a rearwardly open elevator, a rigid foreand-aft frame bar by which the upper elevator frame is supported, and means for so supporting said frame on such bar comprising a two-membered connecting device, consisting of a bracket screwed to the rear frame bar of the upper elevator apron, and a bracket screwed to said rigid frame bar, the two members being pivoted together, and means connecting them for relative adjustment about their pivot.

2. In a harvester elevator, in combination with the lower elevator apron, an upper elevator apron and frame, which at the rear end is suspended above the lower apron for forming a rearwardly open elevator, a rigid fore-and-aft frame bar by which theupper elevator apron frame is supported; means for so supporting said frame on such bar comprising a two-membered connecting device consisting of a bracket mounted rigidly on the rear side bar of the upper elevator apron frame and a bracket screwed to said rigid frame bar, and pivotally connected to the first bracket; a threaded link connecting said two brackets at a distance from their pivotal connection, and adjusting nuts on said link.

3. In a harvester elevator, in combination with the lower elevator apron, an upper ele vator apron and frame which at the rear end is suspended above the lower apron for forming a rearwardly open elevator; a rigid fore-and-aft frame bar by which the upper elevator frame is supported; means for so supporting said frame on such bar comprising a bracket supported on the rigid frame bar and adjustably secured on the rear side bar of the upper apron elevator frame with range of adjustment longitudinally of said frame bar.

In witness whereof I have hereunto set my hand at Plano Illinois this fifteenth day of October, 1909.

JOSEPH BODA.
